Kid, Klipsch owners, biamping etc.

[Sir Terrence the Terrible]

Biamping any speaker can produce good results if done correctly with the right quality equipment and is not a waste of time. Yes a more efficient speaker will generally get more than loud enough for almost anyone with a single amp setup but biamping gives the amps room to breath and to do their thing with ease which can produce a more ease of presentation and let the equipment run at its best without as much heat build up and such.. And as Mr Peabody said he was able to turn the horns down in order to balance things out so in his case it helped in more that one way.

The simplest solution is to buy one amp with enough power that you have the headroom "to let the system breathe", and to give the sound that ease of presentation. There is no audible advantage to bi-wiring any speaker, the internal crossover is still at play in this case. .

Personally, I don't think bi-wiring is the cure for a poor inter-driver balance - a problem with some models in the Klipsch line. Rather than bi-wiring, there are a number of crossover and driver upgrades for the Heresy that are cheaper and easier to pull together, with definite sonic benefits. One cheap way I have read about involved stuffing a bit of toilet paper in the midrange horn. I read that on the Klipsch forum a long time ago.


Real bi-amping requires a bypass of the internal crossover, and active or passive filters to keep the highs out of the bass driver(and amp), and lows out of the tweeter(and amp). The crossover should be set before the amplification. This is not the setup the OP is describing, so I am doubtful of the conclusions. Powered professional monitors provide true bi-amping as they operate exactly like the before mentioned.

The OP has bi-wired his speakers, not Bi amped them. There is a difference.

I remember the Powered Advent Speaker which was truly bi-amped. You would run an interconnect from the preamp to the speakers. The crossover would divide the signal and send the upper frequencies to the tweeter amp and the lows to the woofer amp. The tweeter amp was of lower wattage than the woofer amp. As I remember a very powerful and dynamic sound.

I actually think that he was referring to bi amping not bi wiring since he is using multiple amplifiers to separately drive his low end and high end and even though he is still using the internal crossovers what he is doing is true bi amping its just not with active crossovers he is still using the passive crossovers in the cabinets which is fine if you are satisfied with the crossover point and have not done a lot of modifying of the speakers. Yes passive crossovers do drain some power but there are not very many active crossovers in the home audio world that are very clean when used with high end equipment and most pro sound unit make you switch all the connections going from RCA to XLR unless all of your home stuff runs XLR connectors already then it changes things but I would say you would have to go with quite a pricey pro sound unit for it not to ad distortions or be as quiet as the rest of the components.

Yes he is using two amps but true biamping is preamp to crossover and highs to one amp and lows to the other amp. Then the output of the high frequency amp to the tweeter and low frequency amp to the woofer. A 3 way speaker would need to be triamped. He is doing a pseudo biamping.

You are correct JM, pseudo biamping, but more appropriately bi-wiring.
